Patented Dec. 39, I 1930 STATES PATET oFFiE ELMER L. SCHUMACHER, FSOU'JI-LBRIDGE, MASSACHUSETTS, ASSIGNOR TO AMERICAN GPTICAL COMPANY, OFSOUTHBBIDGE, MASSAGI'iUSF-ITS, A VOLUNTARY ASSOCIA- TION OFLz'EASSACEZUSETTS OPHTHALMIC MOUNTING Application filed January 9, 1928.

This invention relates to improvements in parts for ophthalmic mountingsand has particular reference to supporting a metallic member on acomposition temple or similar part and the process of making same.

The principal object of the invention is to provide reinforcing meansfor forming a seat for a metallic member adjacent the front end of atemple for an ophthalmic mounting or a similar part. 7

Another object ofv the invention is to provide an additional amount ofcomposition material adjacent the en-dpiece 0r hinge end of acomposition temple or similar'part formed of tubular stock reinforcedwith metal so that a suitable seat may be formed'in the compositionforseating a metallic part.

Another object is to form a part of an ophthalmic mounting of plaincellulose tubing reinforced with metal and treating the tubing to giveit a mottled effect when finished.

Another object is to provide simple, efiicient and economical meanswhereby a composition member reinforced with metal may be formed oftubular composition of even thickness throughout its length and havesufficient material adjacent its front end for supporting an endpiece orhinge member or other part.

Other objects and advantages of the invention will become apparent fromthe following specification taken in connection with the accompanyingdrawings, and it will be apparent that many changes in the steps of theprocess and in the arrangement and construction of the parts may be madewithout departing from the spirit of the invention as expressed in theaccompanying claims. I, therefore, do not wish to be limited to theexact details and arrangements shown, the preferred forms and steps ofthe process only having been shown by way of illustration.

Referring to the accompanying drawings:

Prior to the present invention it was neces sary to form a reinforcedcomposition temple having a mottled efiect from sheet stool; as it wasimpossible to obtain mottled composition in tubular form. The processinvolved for forming a finished temple was to secure a metallic corewithin a groove formed be tween two pieces of mottled composition bysecuring the two pieces together with a suit able adhesive and thenshaping the composition to the desired form by milling, filing and otherexpensive operations.

The present invention obviates these expensive operations by forming areinforced temple from a tubular composition which requires no millingor shaping throughout its length and which is treated prior to thepolishing and finishing to give it a mottled appearance. It is alsoreinforced adjacent the hinge connection to provide a rigid and neatappearing hinge support.

Referring more particularly to the drawings, the finished temple 1 isformed by inserting the metallic core 2 having a flattened portion 8within, a composition tube 1. The flattened portion 3 when pressedwithin the tube 4L causes thetube to flatten as indicated at 5 in Fig;3. A reinforcing block 6 of a composition similar to the tube a issecured to the flattened end 5 by a suitable adhesive such as liquidcelluloid, as indicated in Figs. 4c and 5, and is then recessed as at 7in Figs. 6 and 'Z to form a seat for the endpiece or hinge member 8. Thehinge member 8 is then posiblend with the tube lal 'Qli to lit the bevelon the endpiece 11, it icing" formed prior understood that the ear loopis to its being fitted to the frame,

The tinting operation accomplished by brushing a colored celluloseliquid or the like over portions of the. s ace of the plain composition,as illustrated in F 11. The cellulose liquid is absorbed by and blendedwith the composition so that when the surface is highly polished it willhave a mottled appearance:

From theiorcgoing des ription it wi' seen that I have provided 2'. bl iand efficient means for o culties of prior art tem and for obtaining a:neat appearing and durable construction.

Having described my invention, I claim:

1. The process of making a part for an ophthalmic mounting comprisingforming a metallic core with a fliLttGDQd'POItlOH: adjacent one end,pressing a nonanetallic' tube over the metallic core and flattenedportion tocause the tube to flatten over the flattened portion of themetallic core, securing a nonmetallic reinforcing member to theflattened portion of the tube, shaping out a recess for a metallicmember therein, riveting a metallic member in the recess and throug'hthe core and shaping'iu) the remaining portion of the reinforcing memberto blend it with the nonmetallictube and metallic member.

2. The process of making a part for an ophthalmic mountingcomprisingforming a. metallic core with a flattened portion adjacent one end,pressing anon-metallic tube over the metallic core and flattened portionto cause the tube to flatten overthe flattened portion of the metalliccore, securing a nonmetallic reinforcing member to the flattened portionof the tube, shaping out a recess for a metallic member therein,riveting a metallic member in the recess and through the core,

shaping up the ren'iaining portion of thereinliorcing member to blenditwith the nonmetallic tube and metallic member, and tinting the blendedreinforcing member and tube to give them a mottled appearance.

3. A part for an ophthalmic mounting comprising a tubular temple sidewith a core in said tube, said core and temple side being widenedadjacent the hinge joint end of the temple side, a' building-up memberon the temple side over the widened portion, and a hinge ear secured tosaid bulldmg-up member, the said securing means being attached to thecore.

"4. A part for an ophthalmic mounting comprising a tubular temple sidewith a solid core in said tube, said core and templeside being widenedadjacent the hinge jointend of the temple side, a building-up member onthe temple side over the idened portion, and av hinge ear secured tosaid building-up member, the securing means passing through the solidcore.

5. The process of making a part for an ophthalmic mounting comprisingforming a metallic core with a flattened portion adja cent one end,pressing a non-metallic tube over the metallic core to cause the tube toflatten over the flattened portion of the core, secining a non-metallicreinforcing member to the flattened portion of the tube, and securing ahinge member to the reinforcing member and shaping up the reinforcingmember to blend with the tube.

(5. A part for an ophthalmic mounting comprising a tubular temple sidewith a core in said tube, said core and temple side being widenedadjacent the hinge joint end of the temple side, a building-up member onthe temple side over the widened portion, and a hinge ear secured tosaid building'up member, the securing means passing through the core.
